Every data type in a GeometryFlow graph requires a unique integer to identify the type. This enum defines various integer ranges used by the known data/node libraries.
namespace UE { namespace GeometryFlow { enum EDataTypes { Integer = 0, Float = 1, Double = 2, Vector3f = 20, Vector3d = 21, Name = 30, BaseMeshProcessingTypes = 1000, BaseMeshProcessingTypesEditor = 2000, UserDefinedTypes = 10000, } } }
